论文摘要
在这项工作中，我们提供了一个真正的相对论量子传送方案，其经典通信组件利用了量子场的相对论因果传播。因此，量子传送是通过构造完全相对论的。我们的方案基于Unruh-Dewitt Qubit探测器模型，在该模型中，要传送的量子状态与Alsing和Milburn考虑的实际量子模式相关，而不是通过ALSING和MILBURN考虑的场模式[PRL 91，180404（2003）]。我们表明，（相对论）量子信息中的现有作品，包括一声和渐近通道能力的良好定义，以及量子场理论的代数表述，已经为我们提供了所有必要的成分，以相对直接的方式构建基本相对论传播方案。
In this work we provide a genuine relativistic quantum teleportation protocol whose classical communication component makes use of relativistic causal propagation of a quantum field. Consequently, the quantum teleportation is fully relativistic by construction. Our scheme is based on Unruh-DeWitt qubit detector model, where the quantum state being teleported is associated to an actual qubit rather than a field mode considered by Alsing and Milburn [PRL 91, 180404 (2003)]. We show that the existing works in (relativistic) quantum information, including good definitions of one-shot and asymptotic channel capacities, as well as algebraic formulation of quantum field theory, already provide us with all the necessary ingredients to construct fundamentally relativistic teleportation protocol in relatively straightforward manner.
